论文摘要
已经提出了用于Bose-Einstein冷凝物（BEC）的量子干涉法和量子信息处理，但是以复杂的方式描述了BEC，例如使用量子场理论或使用非线性微分方程。非线性量子力学与干涉和量子信息处理的核心叠加原理并不吻合，但可以兼容。因此，我们为量子门建立了严格的基础，通过求解进化方程，然后使用该基础，并结合量子对照技术和适当的状态采样技术，以设计可行的非线性Hadamard Gates，从而设计可行的非线性Hadamard Gates，从而可以可行，即可行，即高对比，非线性的Ramsey Ramsey Intermey intertorementry。我们的BEC干涉法和量子逻辑的方法通过扩大到非线性量子力学的情况来改变范式，我们将其应用于BEC干涉法和量子信息处理的情况。
Quantum interferometry and quantum information processing have been proposed for Bose-Einstein condensates (BECs), but BECs are described in complicated ways such as using quantum field theory or using a nonlinear differential equation. Nonlinear quantum mechanics does not mesh well with the superposition principle at the heart of interferometry and quantum information processing but could be compatible. Thus, we develop a rigorous foundation for quantum gates, obtained by solving the equation for evolution, and then we employ this foundation, combined with quantum-control techniques and appropriate state-sampling techniques, to devise feasible nonlinear Hadamard gates and thereby feasible, i.e., high-contrast, nonlinear Ramsey interferometry. Our approach to BEC interferometry and quantum logic shifts the paradigm by enlarging to the case of nonlinear quantum mechanics, which we apply to the cases of BEC interferometry and quantum information processing.
